Repeatitive Dream: Carnival of Creatures

I have had the same dream every September of 6th, 7th, 8th, & 9th grade. It always starts out with me walking on the sidewalk singing quietly pulling a cooler behind me. I walk right up to the soccer field of my elementrary school where the spring carnival was going on. Familiar students, adults and teachers all having a great time. The spinning strawberry, the blown up race course, gold fish prizes everything that a carnival consists of. I walk through evrything I just described, still pulling the cooler. Friends kept asking if I brought treats or asked what was in the cooler and I would reply you'll see but in my head I had no idea what was in the cooler. I walked straight to the office and stood in front of it waiting for something. Standing right beside a huge walk way from the street a black semi truck with red trimming pulls up right in front of me. A man with ram horns, a black tux, a red tie and a tall hat came out of the cab. Kids and adults started to crowd around the truck. The horned man started "Ladies and Gentlemen.." I cant remember all he said but I started to run through the crowed begging people to leave but they wouldnt move they were all jsut stood there in awe. Then he said " Here they are..." and he opened the back doors of the truck. And creatures flew, ran, crawled out of the truck terrorizing everyone. Kids screaming and the dream would ended there. But when I was in the 9th grade It started the same, me walking on the sidewalk, singing, not knowing what was in the cooler, just a little more determined. I walked up to the carnival telling people to leave but no one would listen so I went to the street where I knew the truck made its entrance. I stood there waiting with the cooler. Finally I saw the semi speeding down the street. But this time the horned man wasnt driving..he was standing on top of the cab. Wearing the same exact outfit but he had a beard...as if it had been awhile since I saw him last. The truck approached me and the horned man jumped down and He said "Hello 'BlackEyedAngel', You cant stop me and my friends this time". I ran back up to the school screaming for everyone to leave and they all started to run and scream because once I said that, the horned man unleashed all the creatures. I finally opened my cooler. It had stakes, crosses and a dagger with pretty jewels around the hand part. I ran into the school and hid in a classroom. Everyyone did. Everyone was hiding in all of the classrooms. There were kids from my class in the same classroom as I was in. I passed out all the weapons and said I dont know what is going on or what they want but use these if you have to. We sat there waiting. We started to hear something burning..you know like the crackling and popping noise. I started to feel warm like I was next to a campfire and then I heard him..the horned man in the hallway. I ran to the door just to make sure it was locked. He called my name " 'BlackEyedAngel'.." he said it five times. I interupted the sixth one by entering the hallway with the jewelled dagger. I was at one end of the hall and he was at the other. He said "'BlackEyedAngel' you cant save them. Your not one of them.." I screamed " Just stop it!" he looked at me and said"'BlackEyedAngel' you loook lovely tonight.." and bolted right towards me. I stuck the dagger right out in front of me and shut my eyes. He grabbed me from behind and whispered"Dont cry, I've got you now.." and bit inbetween my neck and shoulder. Thats when I woke up. I havent had that dream since freshman year. I dont know if it means anything or if it was just my imagination. I had that last dream in October instead of September that year.
